Abstract

The invention discloses a high-voltage circuit breaker energy storage device health state evaluation method based on energy storage current analysis. The high-voltage circuit breaker energy storage device health state evaluation method comprises the steps that: an open type current sensor is clamped on a power line of an energy storage motor for acquiring a current in the whole operation process of the motor; a current value acquired by means of the open type current sensor is transmitted to a mechanical characteristic tester; and the mechanical characteristic tester records a current waveformof the motor. According to the high-voltage circuit breaker energy storage device health state evaluation method, an online monitoring mode is adopted, a measuring device is directly arranged on a circuit breaker energy storage device and can be implemented without dismounting a spring; the measuring device is arranged in the operation process of a circuit breaker, and normal operation of the circuit breaker is not influenced; and the current of the energy storage motor of the circuit breaker is monitored in real time, and the integrity and continuity of detection data are ensured, so that the defect trend of the energy storage device is analyzed and judged, the economical efficiency of equipment replacement is achieved, and the defect expansion is avoided.

Description

technical field [0001] The invention belongs to the detection technology of the running state of a high-voltage circuit breaker, relates to the field of detection of the health state of a high-voltage circuit breaker energy storage device, and in particular relates to a method for evaluating the health state of a high-voltage circuit breaker energy storage device based on energy storage current analysis. Background technique [0002] As the breaking device in the power system, the high-voltage circuit breaker is an indispensable device in the power distribution device of the power plant and the substation. During normal operation, it is used to switch the operation mode, connect equipment or lines to the circuit or exit the operation, and plays a control role. When the equipment and lines fail, it can be cut off quickly to ensure the normal operation of the fault-free parts and play a protective role. The high-voltage circuit breaker shoulders the dual tasks of control and ...
